Device-Independent Handshake Protocol

A test suite to verify the quantum capabalities of unknown devices.

Motivation

The quantum internet will enable long-distance quantum cryptography, teleportation, and distributed quantum computation. Inevitably, long-distance quantum communications will require a large network of intermediary quantum-enabled devices [1]. As the size the size of quantum networks increases, a handshake protocol will be required to establish connections with unknown devices. It will be an important part of this handshake to determine whether a device can faithfully perform simple quantum communications tasks.

Objectives

  1. Develop a device-independent handshake protocol to verify quantum systems
    • Verifies dimension, superposition, incompatible measurements, and entanglement.
    • Applies genericly to future quantum networks of any design.
    • Protocol is documented on the Verification Protocol page.
  2. Create a python module to perform the handshake protocol
    • The device_independent_test module provides a HandShake api for running varios device-independent tests for bipartite communication scenarios.
    • Our code is found at: https://github.com/ChitambarLab/QiskitSummerJam2020
    • Software documentation is located under the 'Software Documentation' tab on the left-hand side
  3. Prototype and test the handshake with Qiskit
    • Descriptions of test implementations on the Qiskit simulator and IBM quantum computers is found under the Qiskit Examples tab.
    • The theory behind device independent tests is documented under the 'Device-Independence Theory' tab on the left-hand size.

Codebase Guide

The best way to consume our project is through this website. All notebooks have been converted into a static website made with mkdocs and hosted with GitHub pages.

Our codebase is found on github, https://github.com/ChitambarLab/QiskitSummerJam2020.

The device_independent_test module contains python software for running our HandShake.test_all() test suite in a generic manner. The quantum_communicator module serves as the interface between our HandShake module and the quantum devices. For the scope of this project we ran all tests for quantum devices on a single quantum machine.

Please review the Software Documentation, Qiskit Examples and Usage Guide for details regarding project use.
